green chromasis problem

[ericosuave]

i just bought 2 green chromises.. and one looks fine but the other developed this vertical line on his back.. looks brown from what i can see.. he was eating fine and swimming around fine earlier.. but than he separated from the other chromis and hid in the rocks and has been there for like 4 hours now. Is the poor thing gonna die? what can i do to save him! plz help!!

No problem, I moved it.

other than hiding, what is his behavious like? does he look to be breathing rapidly or laborously? do his scales look slimy or normal? and just because a lot of people get it confused, by verticle, you mean a line like this, | and not like thise, ---, correct?

yeah.. it was a | line.. but he died but just in case.. i would like to know what to do next time. what should i have done?
